This is a simple circuit with two buttons and two LEDs to control the D945GCLF Intel motherboard. Both power and reset buttons are included as well as hard disc activity LED and power status LED. The special feature included is the sleep effect of Apple laptops on the power LED!
Design and Implementation
The design goals were:
- simple to connect to the motherboard;
- power button;
- the reset button;
- possible front usb sockets;
- Hdd LED;
- Power LED with sleep effect.
Both power and reset buttons are included in the circuit as well as the LEDs and a pic 12F6xx microcontroller to generate the effect. No USB sockets are included. The connection to the motherboard is also easily done with a flat cable.
The circuit connects directly to the motherboard front panel header with SV1.
Each pin function is enumerated in the user’s manual and also here for convenience.
